Cache modification via unchecked AJAX action handlers
Published Jun 11, 2024 · Updated Apr 28, 2026
Missing authorization in Fastly for WordPress 1.2.25 and earlier allows remote attackers to modify cache state through AJAX actions. The plugin's AJAX action handlers invoke administrator-intended cache functions without checking the caller's capability. Wordfence reports that subscriber-level access is required, while Patchstack's CVSS assessment treats the path as unauthenticated; the bounded consequence is cache modification.
